Referring now to the drawings in general, the illustrations are for the purpose of describing one or more preferred embodiments of the invention and are not intended to limit the invention thereto.

In some embodiments, the present invention provides a portable battery pack including a battery enclosed by, e.g., inside of, a wearable and replaceable pouch or skin, wherein the pouch or skin can be provided in different colors and/or patterns. Namely, a set of multiple interchangeable pouches or skins can be provided with one battery unit. This feature is particularly beneficial when it is required that the portable battery pack blend into different environments, such as in military applications. In one example, if the portable battery pack is used in a jungle or wilderness environment, the battery can be placed inside a camouflage pouch or skin. In another example, if the portable battery pack is used in an arctic environment, the battery can be placed inside a white-colored pouch or skin. In yet another example, if the portable battery pack is used in a desert environment, the battery can be placed inside a sand-colored pouch or skin.

Representative camouflages include, but are not limited to, universal camouflage pattern (UCP), also known as ACUPAT or ARPAT or Army Combat Uniform; MultiCam, also known as Operation Enduring Freedom Camouflage Pattern (OCP); Universal Camouflage Pattern-Delta (UCP-Delta); Airman Battle Uniform (ABU); Navy Working Uniform (NWU), including variants, such as, blue-grey, desert (Type II), and woodland (Type III); MARPAT, also known as Marine Corps Combat Utility Uniform, including woodland, desert, and winter/snow variants; Disruptive Overwhite Snow digital camouflage, urban digital camouflage, and Tactical Assault Camouflage (TACAM).

Therefore, an aspect of the portable battery pack is that it provides a battery in combination with one or more wearable and replaceable pouches or skins, wherein the one or more pouches or skins can be different colors and/or patterns.

Another aspect of the portable battery pack is that the battery has one or more leads that can be flexed repeatedly in any direction without breaking or failing. This means the portable battery pack is operable to deliver energy from the battery to power consuming devices located in different areas of the load bearing equipment. Similarly, the portable battery pack is operable to receive energy from charging devices located in different areas of the load bearing equipment to the battery.

Yet another aspect of the portable battery pack is that the battery and pouch or skin are lightweight and contoured for comfortable wearing or ease of fastening to other equipment, such as a backpack or body armor.

Still another aspect of the portable battery pack is that the pouch or skin can be MOLLE-compatible. “MOLLE” means Modular Lightweight Load-carrying Equipment, which is the current generation of load-bearing equipment and backpacks utilized by a number of NATO armed forces. The portable battery pack can also be made to affix to other equipment (e.g., chair or seat, boat or kayak, helmet) or a user's body (e.g., back region, chest region, abdominal region, arm, leg) using straps, snaps, hook and loop tape, snaps, ties, buckles, and/or clips for other applications.

FIGS. 1-3 are perspective views of an example of the portable battery pack 100 that includes a battery enclosed by a wearable pouch or skin. For example, portable battery pack 100 includes a pouch 110 for holding a battery 150. Pouch 110 is a wearable pouch or skin that can be sized in any manner that substantially corresponds to a size of battery 150. In one example, pouch 110 is sized to hold a battery 150 that is about 9.75 inches long, about 8.6 inches wide, and about 1 inch thick.

In a preferred embodiment, pouch 110 is formed of a flexible, durable, and waterproof or at least water-resistant material. For example, pouch 110 can be formed of polyester, polyvinyl chloride (PVC)-coated polyester, vinyl-coated polyester, nylon, canvas, PVC-coated canvas, or polycotton canvas. In one embodiment, pouch 110 is formed of a material that is laminated to or treated with a waterproofing or water repellant material (e.g., rubber, PVC, polyurethane, silicone elastomer, fluoropolymers, wax, thermoplastic elastomer). Additionally or alternatively, pouch 110 is treated with a UV coating to increase UV resistance. The exterior finish of pouch 110 can be any color, such as white, brown, green, orange (e.g., international orange), yellow, black, or blue, or any pattern, such as camouflage, as provided herein, or any other camouflage in use by the military, law enforcement, or hunters. For example, in FIGS. 1-3, pouch 110 is shown to have a camouflage pattern. In one embodiment, the exterior of pouch 110 includes a reflective tape, fabric, or material. Advantageously, the reflective tape, fabric, or material improves visibility of the user in low-light conditions.

Pouch 110 has a first side 112 and a second side 114. Pouch 110 also includes an opening 116, which is the opening through which battery 150 is fitted into pouch 110. In the example shown in FIGS. 1-3, opening 116 is opened and closed using a zipper, as such pouch 110 includes a zipper tab 118. Other mechanisms, however, can be used for holding opening 116 of pouch 110 open or closed, such as, a hook and loop system (e.g., Velcro®), buttons, snaps, hooks, ties, clips, buckles, and the like. Further, an opening 120 (see FIG. 2, FIG. 3, FIG. 5) is provided on the end of pouch 110 that is opposite opening 116. For example, opening 120 can be a 0.5-inch long slit or a 0.75-inch long slit in the edge of pouch 110. In one embodiment, the opening 120 is finished or reinforced with stitching. In another embodiment, the opening 120 is laser cut.

The battery 150 includes at least one lead. In one example, battery 150 is a rechargeable battery with two leads 152 (e.g., leads 152 a, 152 b) as shown in FIGS. 2-3. Each lead 152 can be used for both the charging function and the power supply function. In other words, leads 152 a, 152 b are not dedicated to the charging function only or the power supply function only, both leads 152 a, 152 b can be used for either function at any time or both at the same time. In one example, one lead 152 can be used for charging battery 150 while the other lead 152 can be used simultaneously for powering equipment, or both leads 152 can be used for powering equipment, or both leads 152 can be used for charging battery 150.

Each lead 152 is preferably operable to charge and discharge at the same time. In one example, a Y-splitter with a first connector and a second connector is attached to a lead 152. The Y-splitter allows the lead 152 to supply power to equipment via the first connector and charge battery 150 via the second connector at the same time. Thus, the leads 152 are operable to allow power to flow in and out of the battery simultaneously.

In a preferred embodiment, a dust cap is used to cover a corresponding lead. Advantageously, the dust cap protects the connector from dust and other environmental contaminants that may cause battery failure in the field.

The battery 150 is operable to be charged using at least one charging device. In a preferred embodiment, the at least one charging device is an alternating current (AC) adapter, a solar panel, a generator, a portable power case, a fuel cell, a vehicle battery, a rechargeable battery, and/or a non-rechargeable battery. Examples of a portable power case are disclosed in US Publication No. 20170229692 and U.S. application Ser. No. 15/664,776, each of which is incorporated herein by reference in its entirety. In one embodiment, the battery 150 is connected to the at least one charging device through a direct current-direct current (DC-DC) converter cable.

In another embodiment, the battery 150 is operable to be charged via inductive charging. In one embodiment, the battery 150 is operable to be charged using an inductive charging mat. In an alternative embodiment, the battery is operable to be charged using an inductive puck worn in a pocket, on the back of a helmet, or in a rucksack. In one embodiment, the inductive puck is powered using a DC power source. Advantageously, this reduces the number of cables required for a user, which prevents users from accidentally disconnecting cables (e.g., when getting in and out of spaces like vehicles). Additionally, this allows a user to use proximity charging, which allows the user to focus on the task at hand instead of spending a few seconds connecting the battery to a charging device, which may be located behind the user in a rucksack. Further, this embodiment eliminates the possibility of reverse polarity and arcing between connectors caused by the electrical potential. The inductive puck is operable to charge additional power consuming devices carried by a user (e.g., a smartphone, a tablet).

In one embodiment, the battery 150 is operable to be charged by harvesting ambient radiofrequency (RF) waves. Alternatively, the battery 150 is operable to be charged by capturing exothermic body reactions (e.g., heat, sweat). In one embodiment, the battery 150 is operable to be charged using thermoelectric generators, which use temperature differences between the body and the external environment to generate energy. In another embodiment, the battery 150 is operable to be charged using sweat (e.g., using lactate). In an alternative embodiment, the battery 150 is operable to be charged using friction (e.g., triboelectric effect) or kinetic energy. In yet another example, the battery 150 is operable to be charged by a pedal power generator. In one embodiment, the battery 150 is connected to the pedal power generator through a direct current-direct current (DC-DC) converter cable.

The battery 150 is also operable to be charged using energy generated from running water and wind energy. In one embodiment, the wind energy is generated using an unmanned aerial system or drone on a tether. In an alternative embodiment, the wind energy is generated using a drive along turbine.

With respect to using battery 150 with pouch 110, first the user unzips opening 116, then the user inserts one end of battery 150 that has, for example, lead 152 b through opening 116 and into the compartment inside pouch 110. At the same time, the user guides the end of lead 152 b through opening 120, which allows the housing of battery 150 to fit entirely inside pouch 110, as shown in FIG. 1. Lead 152 a is left protruding out of the unzipped opening 116. Then the user zips opening 116 closed, leaving zipper tab 118 snugged up against lead 152 a, as shown in FIG. 2 and FIG. 3. FIG. 2 shows portable battery pack 100 with side 112 of pouch 110 up, whereas FIG. 3 shows portable battery pack 100 with side 114 of pouch 110 up.

As previously described, battery 150 has at least one lead 152. In one embodiment, pouch 110 has an opening 120 for each corresponding lead 152. In one example, the battery 150 has four leads 152 and the pouch 110 has four openings 120 corresponding to the four leads 152. Alternatively, pouch 110 utilizes the zippered opening 116 to secure one lead 152 and has an opening 120 for each remaining lead 152. In one example, the battery 150 has four leads 152 and the pouch 110 has three openings 120 for three of the four leads 152. The remaining lead 152 is secured by the zipper.

In another embodiment, pouch 100 has a seal around an opening 120 for a corresponding lead 152. The seal is tight around the lead 152, which prevents water from entering the pouch through the opening 120. In one embodiment, the seal is formed of a rubber (e.g., neoprene).

In a preferred embodiment, pouch 110 of portable battery pack 100 is MOLLE-compatible. In one embodiment, pouch 110 incorporates a pouch attachment ladder system (PALS), which is a grid of webbing used to attach smaller equipment onto load-bearing platforms, such as vests and backpacks. For example, the PALS grid consists of horizontal rows of 1-inch (2.5 cm) webbing, spaced about one inch apart, and reattached to the backing at 1.5-inch (3.8 cm) intervals. In one embodiment, the webbing is formed of nylon (e.g., cordura nylon webbing, MIL-W-43668 Type III nylon webbing). Accordingly, a set of straps 122 (e.g., four straps 122) are provided on one edge of pouch 110 as shown. Further, rows of webbing 124 (e.g., four rows 124) are provided on side 112 of pouch 110, as shown in FIG. 2. Additionally, rows of slots or slits 126 (e.g., four rows of slots or slits 126) are provided on side 114 of pouch 110, as shown in FIG. 3. In a preferred embodiment, the set of straps 122, rows of webbing 124, and rows of slots or slits 126 replicate and duplicate the MOLLE underneath the portable battery pack on the load bearing equipment. Advantageously, this allows for minimal disruption to the user because the user can place additional gear pouches or gear (e.g., water bottle, antenna pouch) on the MOLLE of the portable battery pack in an equivalent location.

In other embodiments, the portable battery pack is made to affix to other equipment (e.g., chair or seat, boat or kayak, helmet) or a user's body (e.g., back region, chest region, abdominal region, arm, leg) using straps, snaps, hook and loop tape, snaps, buckles, ties, and/or clips. In one example, the portable battery pack is made to affix to a seat of a kayak using at least one strap and at least one side-release buckle. In another example, the portable battery pack is made to affix to a user's body using two shoulder straps. In yet another example, the portable battery pack includes two shoulder straps, a chest strap, and a side-release buckle for the chest strap.

FIG. 4 shows details of side 112 of pouch 110 and of the edge of pouch 110 that includes opening 116. FIG. 4 shows opening 116 in the zipper closed state. Again, four rows of webbing 124 are provided on side 112 of pouch 110. FIG. 5 also shows details of side 112 of pouch 110 and shows the edge of pouch 110 that includes opening 120. FIG. 6 shows details of side 114 of pouch 110 and shows the edge of pouch 110 that includes opening 116. FIG. 6 shows opening 116 in the zipped closed state. Again, four rows of slots or slits 126 are provided on side 114 of pouch 110.

In another embodiment, the portable battery pack is made to affix to a plate carrier, body armor, or vest with at least one single width of zipper tape sewn on the front panel or the back panel (e.g., JPC 2.0™ by Crye Precision) as shown in FIGS. 7A-7B. FIG. 7A shows details of side 112 of pouch 110 including a single width of zipper tape 190 a and a zipper slider 192 a. The single width of zipper tape 190 a mates with a corresponding single width of zipper tape on the plate carrier, body armor, or vest. FIG. 7B shows details of side 114 of pouch 110 including a single width of zipper tape 190 b and a zipper slider 192 b. The single width of zipper tape 190 b mates with a corresponding single width of zipper tape on the plate carrier, body armor, or vest.

FIG. 8 shows a side perspective view of the portable battery pack 100 affixed to a vest 800 using zippers. The single width of zipper tape 190 a is shown mated with a corresponding single width of zipper tape 194 a on a right side of the vest 800 using zipper slider 192 a, thereby attaching the portable battery pack 100 to the vest 800. Similarly, the single width of zipper tape 190 b (not shown) is mated with a corresponding single width of zipper tape 194 b (not shown) on a left side of the vest 800 using zipper slider 192 b (not shown).

FIGS. 9A-9E illustrate various other views of wearable pouch 110 of the portable battery pack 100. FIG. 9A shows a view (i.e., “PLAN-A”) of side 112 of pouch 110. FIG. 9B shows a side view of pouch 110. FIG. 9C shows a view (i.e., “PLAN-B”) of side 114 of pouch 110. FIG. 9D shows an end view (i.e., “END-A”) of the non-strap end of pouch 110. FIG. 9E shows an end view (i.e., “END-B”) of the strap 112-end of pouch 110. FIG. 10 is an exploded view of an example of battery 150 of the portable battery pack 100. Battery 150 includes a battery element 164 that is housed between a battery cover 154 and a back plate 162. Battery element 164 supplies leads 152 a, 152 b. The battery element 164 is formed of a plurality of sealed battery cells or individually contained battery cells, i.e. batteries with their own cases, removably disposed therein. In a preferred embodiment, the battery cells are electrochemical battery cells, and more preferably, include lithium ion rechargeable batteries. In one embodiment, the battery cells are lithium metal or lithium ferrous phosphate cells. In an alternative embodiment, the battery cells are all-solid-state cells (e.g., using glass electrolytes and alkaline metal anodes), such as those disclosed in US Publication Nos. 20160368777 and 20160365602, each of which is incorporated by reference in its entirety. In another embodiment, the battery is formed using at least one metal-organic framework. In one embodiment, the battery cells are 18350, 14430, 14500, 18500, 16650, 18650, 21700, or 26650 cylindrical cells. The plurality of battery cells may be constructed and configured in parallel, series, or a combination. The plurality of battery cells may be in one group or more than one group. Advantageously, subdividing the plurality of battery cells into more than one group allows a larger quantity of lithium ion batteries to arrive by air that otherwise could not be transported due to regulations. In one example, the output of battery element 164 can be from about 5 volts DC to about 90 volts DC at from about 0.25 amps to about 10 amps.

The plurality of battery cells is preferably connected to the leads via a battery management system. The battery management system protects the battery from operating outside of a safe operating area by including at least one safety cutoff. The at least one safety cutoff relates to voltage, temperature, state of charge, state of health, and/or current. In another embodiment, the battery management system calculates a charge current limit, a discharge current limit, an energy delivered since last charge, a charge delivered, a charge stored, a total energy delivered since first use, a total operating time since first use, and/or a total number of cycles.

In one embodiment, the plurality of battery cells is removably disposed within the battery cover 154 and the back plate 162. For example, the plurality of battery cells can be replaced if they no longer hold a sufficient charge. In one embodiment, the plurality of battery cells is removably disposed within the battery cover 154 and the back plate 162 as a battery cartridge. In a preferred embodiment, the battery cartridge slides into an opening in the battery cover 154 or the back plate 162 through a battery access panel. In one embodiment, the battery cartridge is a spring-loaded cartridge. Additionally or alternatively, the battery cartridge has flat contacts and pins. The battery cartridge preferably has features that allow the battery cartridge to matingly fit with features in the opening. In another embodiment, the plurality of battery cells is removably disposed within the battery cover 154 and the back plate 162 using a battery holder or a snap connector. In one embodiment, the battery holder or the snap connector is electrically connected to the battery management system via a mating connector (e.g., a rectangular connector), such as those available from Molex® or Powerpole® by Anderson Power.

The battery access panel is preferably accessed within the battery cover 154 or the back plate 162 via a door on hinges, which allows the door to stay anchored to the device. Alternatively, the door is secured to the battery cover 154 or the back plate 162 by screws. The battery access panel preferably contains a gasket that provides a water tight seal when the door is secured to the battery cover 154 or the back plate 162.

Alternatively, the plurality of battery cells is sealed within the battery cover 154 and the back plate 162. In one embodiment, the plurality of battery cells is sealed using an adhesive and/or at least one mechanical fastener (e.g., screws, rivets, pins). In another embodiment, the plurality of battery cells is sealed within the battery cover 154 and the back plate 162 via bonding (e.g., solvent bonding, fusion bonding) and/or welding (e.g., vibration welding, ultrasonic welding).

The battery cover 154 includes a compartment 156 that is sized to receive at least one battery element 164. In a preferred embodiment, the compartment 156 is substantially rectangular in shape with a top hat style rim 158 provided around the perimeter of compartment 156. The battery cover 154 incudes at least one channel formed in the battery cover 154 to accommodate a wire of a corresponding lead. The example in FIG. 10 shows two channels 160 (e.g., channels 160 a, 160 b) formed in battery cover 154 (one on each side) to accommodate the wires of leads 152 a, 152 b passing therethrough. More details of leads 152 and battery cover 154 are shown and described herein below with reference to FIG. 16.

Battery cover 154 and back plate 162 can be formed of plastic using, for example, a thermoform process or an injection molding. Back plate 162 can be mechanically attached to rim 158 of battery cover 154 via, for example, an ultrasonic spot welding process or an adhesive. In one embodiment, a water barrier material (e.g., silicone) is applied to the mating surfaces of rim 158 and back plate 162. In another embodiment, battery cover 154, back plate 162, and/or battery element 164 has a slight curvature or contour for conforming to, for example, the user's vest, backpack, or body armor. In one example, the curvature of the portable battery pack is engineered to match the outward curve of body armor. Advantageously, this means that the portable battery pack does not jostle as the operator moves, which results in less caloric energy expenditure when the operator moves. Alternatively, the battery cover 154, back plate 162, and/or battery element 164 can have a slight outward curvature or contour for conforming to a user's body (e.g., back region, chest region, abdominal region, arm, leg). In yet another embodiment, the battery cover 154, back plate 162, and/or battery element 164 can have a slight outward curvature or contour for conforming to a user's helmet or hat. More details of battery cover 154 are shown and described herein below with reference to FIG. 13 and FIGS. 14A-14D. More details of back plate 162 are shown and described herein below with reference to FIGS. 15A-15C.

As previously described, the housing of the at least one battery includes a battery cover 154 and a back plate 162. In one embodiment, the battery 150 includes more than one battery element 164 encased in the housing. The output voltages of the more than one battery element may be the same or different. In one example, a first battery element has an output voltage of 16.8V and a second battery element has an output voltage of 16.8V. In another example, a first battery element has an output voltage of 16.8V and a second battery element has an output voltage of 5V. Advantageously, including more than one battery element encased in the housing allows a larger quantity of lithium ion batteries to arrive by air that otherwise could not be transported due to regulations.

FIGS. 11-12 are perspective views of battery 150 of the portable battery pack 100 when fully assembled. FIG. 11 shows a view of the battery cover 154-side of battery 150, while FIG. 12 shows a view of the back plate 162-side of battery 150.

FIG. 13 is a perspective view of the side of battery cover 154 that faces battery element 164. FIGS. 14A-14D shows various other views of battery cover 154 of battery 150 of the portable battery pack 100, including example dimensions of battery cover 154. FIG. 14A illustrates a top perspective view of the battery cover of the portable battery pack. FIG. 14B illustrates a cross-section view of the battery cover of the portable battery pack. FIG. 14C illustrates another cross-section view of the battery cover of the portable battery pack. FIG. 14D illustrates yet another cross-section view of the battery cover of the portable battery pack.

FIGS. 15A-15C illustrate various views of back plate 162 of battery 150 and show the contour and example dimensions of back plate 162. FIG. 15A illustrates a cross-section view of the back plate of the battery of the portable battery pack. FIG. 15B illustrates a view of the back plate of the battery of the portable battery pack. FIG. 15C illustrates another view of the back plate of the battery of the portable battery pack. In one example, back plate 162 is about 9.75 inches long, about 8.6 inches wide, and about 0.4 inches thick.

FIG. 16 is a cutaway view of a portion of battery 150, which shows more details of the flexible omnidirectional battery leads 152. Each lead 152 has a connector portion 170 and a wiring portion 172. Wiring portion 172 is electrically connected to battery element 164. In one embodiment, the wiring portion 172 is formed of a saltwater resistant cable. Connector portion 170 can be any type or style of connector needed to mate to the equipment to be used with battery 150 of portable battery pack 100. In a preferred embodiment, the connector portion 170 is a female circular type of connector (e.g., Tajimi™ part number R04-P5f). In an alternative embodiment, at least one connector portion 170 is a male universal serial bus (USB), micro USB, lightning, and/or Firewire connector. In yet another embodiment, the connector portion 170 has an Ingress Protection (IP) rating of IP2X, IP3X, IP4X, IP5X, IP6X, IPX1, IPX2, IPX3, IPX4, IPX5, IPX6, IPX7, or IPX8. More preferably, the connector portion 170 has an IP rating of IPX6, IPX7, or IPX8. IP ratings are described in IEC standard 60529, ed. 2.2 (05/2015), published by the International Electrotechnical Commission, which is incorporated herein by reference in its entirety. In one embodiment, the connector portion meets standards described in Department of Defense documents MIL-STD-202E, MIL-STD-202F published February 1998, MIL-STD-202G published 18 Jul. 2003, and/or MIL-STD-202H published 18 Apr. 2015, each of which is incorporated herein by reference in its entirety.

Wiring portion 172 is fitted into channel 160 formed in battery cover 154 such that connector portion 170 extends away from battery cover 154. A spring 174 is provided around wiring portion 172, such that a portion of spring 174 is inside battery cover 154 and a portion of spring 174 is outside battery cover 154. In one example, spring 174 is a steel spring that is from about 0.25 inches to about 1.5 inches long. Wiring portion 172 of lead 152 and spring 174 are held securely in channel 160 of battery cover 154 via a clamping mechanism 176. Alternatively, the wiring portion 172 of lead 152 and spring 174 are held securely in channel 160 of battery cover 154 using an adhesive, a retention pin, a hex nut, a hook anchor, and/or a zip tie.

The presence of spring 174 around wiring portion 172 of lead 152 allows lead 152 to be flexed in any direction for convenient connection to equipment from any angle. The presence of spring 174 around wiring portion 172 of lead 152 also allows lead 152 to be flexed repeatedly without breaking or failing. The design of leads 152 provides benefit over conventional leads and/or connectors of portable battery packs that are rigid, wherein conventional rigid leads allow connection from one angle only and are prone to breakage if bumped.

In one embodiment, a layer of heat shrink tubing is placed around the wiring portion before the spring is placed around the wiring portion. The heat shrink tubing is preferably flexible. Advantageously, the heat shrink tubing provides additional waterproofing for the battery.

In one embodiment, the battery 150 includes a step down voltage converter. In one example, the battery 150 includes a step down voltage converter from 16.8V to 5V. Advantageously, this allows the portable battery pack to power devices (e.g., smartphones) with a charging voltage of 5V. This also reduces the bulk outside the portable battery pack because the step down voltage converter is housed within the battery element and a separate external voltage converter is not required.

In one embodiment, the wearable pouch includes a material for dissipating heat. Additionally or alternatively, the battery of the wearable battery pack includes at least one layer of a material for dissipating heat. Examples of a material for dissipating heat are disclosed in US Publication Nos. 20170229692 and 20160112004 and U.S. application Ser. No. 15/664,776, each of which is incorporated herein by reference in its entirety.

FIGS. 17A -17D are cross-sectional views of examples of structures that include a material for dissipating heat from electronic devices and/or clothing. The heat-dissipating material can be used in combination with, for example, one or two substrates. For example, FIG. 17A shows a structure 1500 that includes a heat-dissipating layer 1520. The heat-dissipating layer 1520 can be sandwiched between a first substrate 1525 and a second substrate 1530.

The heat-dissipating layer 1520 can be any material that is suitable for dissipating heat from electronic devices and/or clothing. The heat-dissipating layer 1520 can be from about 20 μm thick to about 350 μm thick in one example. In particular embodiments, the heat-dissipating layer 1520 can have a thickness ranging from about 1 mil to about 6 mil, including, but not limited to, 1, 2, 3, 4, 5, and 6 mil, or about 25 μm to about 150 μm, including, but not limited to, 25, 50, 75, 100, 125, and 150 μm. Examples of the heat-dissipating layer 1520 include anti-static, anti-radio frequency (RF), and/or anti-electromagnetic interference (EMI) materials, such as copper shielding plastic or copper particles bonded in a polymer matrix, as well as anti-tarnish and anti-corrosion materials. A specific example of the heat-dissipating layer 1520 is the anti-corrosive material used in Corrosion Intercept Pouches, catalog number 034-2024-10, available from University Products Inc. (Holyoke, Mass.). The anti-corrosive material is described in U.S. Pat. No. 4,944,916 to Franey, which is incorporated by reference herein in its entirety. Such materials can be formed of copper shielded or copper impregnated polymers including, but not limited to, polyethylene, low-density polyethylene, high-density polyethylene, polypropylene, and polystyrene. In another embodiment, the heat shielding or blocking and/or heat-dissipating layer is a polymer with aluminum and/or copper particles incorporated therein. In particular, the surface area of the polymer with aluminum and/or copper particles incorporated therein preferably includes a large percent by area of copper and/or aluminum. By way of example and not limitation, the surface area of the heat-dissipating layer includes about 25% by area copper and/or aluminum, 50% by area copper and/or aluminum, 75% by area copper and/or aluminum, or 90% by area copper and/or aluminum. In one embodiment, the heat shielding or blocking and/or heat-dissipating layer is substantially smooth and not bumpy. In another embodiment, the heat shielding or blocking and/or heat-dissipating layer is not flat but includes folds and/or bumps to increase the surface area of the layer. Alternatively, the heat-shielding or blocking and/or heat-dissipating layer 1520 includes a fabric having at least one metal incorporated therein or thereon. The fabric further includes a synthetic component, such as by way of example and not limitation, a nylon, a polyester, or an acetate component. Preferably, the at least one metal is selected from the group consisting of copper, nickel, aluminum, gold, silver, tin, zinc, and tungsten.

The first substrate 1525 and the second substrate 1530 can be any flexible or rigid substrate material. An example of a flexible substrate is any type of fabric. Examples of rigid substrates include, but are not limited to, glass, plastic, and metal. A rigid substrate may be, for example, the housing of any device. In one example, both the first substrate 1525 and the second substrate 1530 are flexible substrates. In another example, both the first substrate 1525 and the second substrate 1530 are rigid substrates. In yet another example, the first substrate 1525 is a flexible substrate and the second substrate 1530 is a rigid substrate. In still another example, the first substrate 1525 is a rigid substrate and the second substrate 1530 is a flexible substrate. Further, the first substrate 1525 and the second substrate 1530 can be single-layer or multi-layer structures.

In structure 1500 of FIG. 17A, the heat-shielding or blocking and/or heat-dissipating layer 1520, the first substrate 1525, and the second substrate 1530 are bonded or otherwise attached together, by way of example and not limitation, by adhesive, laminating, stitching, or hook-and-loop fastener system.

Advantageously, this layer protects the plurality of battery cells housed in the battery 150 as well as the user. Additionally or alternatively, the material to provide resistance to bullets and/or shrapnel is between the battery element 164 and the back plate 162. Advantageously, this layer provides additional protection to the user.

As previously described, the pouch is preferably formed of a flexible, durable, and waterproof and/or water-resistant material. In one embodiment, seams of the pouch are sewn with an anti-wick or non-wicking thread. In one example, the anti-wick or non-wicking polyester thread is a bonded polyester thread with wax coating (e.g., Dabond®). The wax coating on the thread plugs stitch holes to waterproof seams. Alternatively, seams are joined together using ultrasonic welding.

In one embodiment, the pouch includes drainage holes to remove water from the pouch. The drainage holes are formed of a mesh fabric. Alternatively, the drainage holes are formed using holes with grommets in the waterproof and/or water-resistant material.

In another embodiment, the pouch incudes at least one desiccant to remove moisture from the pouch. In one embodiment, the at least one desiccant includes silica. Alternatively, the at least one desiccant includes activated charcoal, calcium sulfate, calcium chloride, and/or molecular sieves (e.g., zeolites).

The portable battery pack includes leads having a connector portion. As previously described, the connector portion can be any type or style of connector needed to mate to equipment to be used with the battery of the portable battery pack. In one embodiment, a cord connector is used to protect a mated connection between the connector portion and the equipment. Examples of a cord connector include U.S. Pat. Nos. 5,336,106, 5,505,634, and 5,772,462, each of which is incorporated herein by reference in its entirety. Alternatively, a piece of heat shrink tubing is positioned to cover a mated connection between the connector portion and the equipment. In a preferred embodiment, the heat shrink tubing is sized to cover at least 0.25 inch of cabling on either side of the mated connection. Heat is then applied using a heat gun or hair dryer to shrink the tubing and seal the mated connection.

In one embodiment, the portable battery pack includes at least one processor. The at least one processor is preferably housed in the battery. In another embodiment, the at least one processor is incorporated into control electronics used to determine the state of charge (SOC) of the portable battery pack. Examples of state of charge indicators are disclosed in US Publication Nos. 20170269162 and 20150198670, each of which is incorporated herein by reference in its entirety.

FIG. 19 illustrates a block diagram of one embodiment of the control electronics for a state of charge indicator incorporated into the portable battery pack. In this example, the control electronics 2430 includes a voltage sensing circuit 2432, an analog-to-digital converter (ADC) 2434, a processor 2436, the indicator 2440, and optionally a driver 2442.

The voltage sensing circuit 2432 can be any standard voltage sensing circuit, such as those found in volt meters. An input voltage VIN is supplied via the power BUS. In one embodiment, the voltage sensing circuit 2432 is designed to sense any direct current (DC) voltage in the range of from about 0 volts DC to about 50 volts DC. In one embodiment, the voltage sensing circuit 2432 includes standard amplification or de-amplification functions for generating an analog voltage that correlates to the amplitude of the input voltage VIN that is present. The ADC 2434 receives the analog voltage from the voltage sensing circuit 2432 and performs a standard analog-to-digital conversion.

The processor 2436 manages the overall operations of the SOC indicator. The processor 2436 is any controller, microcontroller, or microprocessor that is capable of processing program instructions.

The indicator 2440 is any visual, audible, or tactile mechanism for indicating the state of charge of the portable battery pack. A preferred embodiment of a visual indicator is at least one 5-bar liquid crystal display (LCD), wherein five bars flashing or five bars indicates greatest charge and one bar or one bar flashing indicates least charge. Another example of a visual indicator is at least one seven-segment numeric LCD, wherein the number 5 flashing or the number 5 indicates greatest charge and the number 1 or the number 1 flashing indicates least charge. Alternatively, the at least one LCD displays the voltage of the portable battery pack as measured by the control electronics.

The at least one LCD is preferably covered with a transparent material. In a preferred embodiment, the cover is formed of a clear plastic (e.g., poly(methyl methacrylate)). This provides an extra layer of protection for the at least one LCD, much like a screen protector provides an extra layer of protection for a smartphone. This increases the durability of the at least one LCD. In one embodiment, the at least one LCD is on the housing of the battery. In a preferred embodiment, the housing of the battery includes a waterproof sealant (e.g., silicone) around the cover.

Alternatively, a visual indicator is at least one LED. One preferred embodiment of a visual indicator is a set of light-emitting diodes (LEDs) (e.g., 5 LEDs), wherein five lit LEDs flashing or five lit LEDs indicates greatest charge and one lit LED or one lit LED flashing indicates least charge. In one embodiment, the LEDs are red, yellow, and/or green. In one example, two of the LEDs are green to indicate a mostly full charge on the portable battery pack, two of the LEDs are yellow to indicate that charging will soon be required for the portable battery pack, and one LED is red to indicate that the portable battery pack is almost drained. In a preferred embodiment, at least three bars, lights, or numbers are used to indicate the state of charge.

In one embodiment, the at least one LED is preferably covered with a transparent material. In a preferred embodiment, the cover is formed of a clear plastic (e.g., poly(methyl methacrylate)). This provides an extra layer of protection for the at least one LED. This increases the durability of the at least one LED. In one embodiment, the at least one LCD is on the housing of the battery. In a preferred embodiment, the housing of the battery includes a waterproof sealant (e.g., silicone) around the cover.

One example of an audible indicator is any sounds via an audio speaker, such as beeping sounds, wherein five beeps indicates greatest charge and one beep indicates least charge. Another example of an audible indicator is vibration sounds via any vibration mechanism (e.g., vibration motor used in mobile phones), wherein five vibration sounds indicates greatest charge and one vibration sound indicates least charge.

One example of a tactile indicator is any vibration mechanism (e.g., vibration motor used in mobile phones), wherein five vibrations indicate greatest charge and one vibration indicate least charge. Another example of a tactile indicator is a set of pins that rise up and down to be felt in Braille-like fashion, wherein five raised pins indicates greatest charge and one raised pin indicates least charge.

In one example, the processor 2436 is able to drive indicator 2440 directly. In one embodiment, the processor 2436 is able to drive directly a 5-bar LCD or a seven-segment numeric LCD. In another example, however, the processor 2436 is not able to drive indicator 2440 directly. In this case, the driver 2442 is provided, wherein the driver 2442 is specific to the type of indicator 2440 used in the control electronics 2430.

Additionally, the processor 2436 includes internal programmable functions for programming the expected range of the input voltage VIN and the correlation of the value the input voltage VIN to what is indicated at the indicator 2440. In other words, the discharge curve of the portable battery pack can be correlated to what is indicated at indicator 2440. In one embodiment, the processor 2436 is programmed based on a percent discharged or on an absolute value present at the input voltage VIN.

In one embodiment, the control electronics includes at least one antenna, which allows the portable battery pack to send information (e.g., state of charge information) to at least one remote device (e.g., smartphone, tablet, laptop computer, satellite phone) and/or receive information (e.g., software updates, activation of kill switch) from at least one remote device. The at least one antenna provides wireless communication, standards-based or non-standards-based, by way of example and not limitation, radiofrequency, Bluetooth®, ZigBee®, Near Field Communication, or similar commercially used standards.

FIG. 20A illustrates a block diagram of an example of an SOC system 2500 that includes a mobile application for use with a portable battery pack. The SOC system 2500 includes a battery 150 having a communications interface 2510.

The communications interface 2510 is any wired and/or wireless communication interface for connecting to a network and by which information may be exchanged with other devices connected to the network. Examples of wired communication interfaces include, but are not limited to, USB ports, RS232 connectors, RJ45 connectors, Ethernet, and any combinations thereof. Examples of wireless communication interfaces include, but are not limited to, an Intranet connection, Internet, ISM, Bluetooth® technology, Wi-Fi®, WiMAX®, IEEE 802.11 technology, radio frequency (RF), Near Field Communication (NFC), ZigBee®, Infrared Data Association (IrDA) compatible protocols, Local Area Networks (LAN), Wide Area Networks (WAN), Shared Wireless Access Protocol (SWAP), any combinations thereof, and other types of wireless networking protocols.

The communications interface 2510 is used to communicate, preferably wirelessly, with at least one remote device, such as but not limited to, a mobile phone 2130 or a tablet 2132. The mobile phone 2130 can be any mobile phone that (1) is capable of running mobile applications and (2) is capable of communicating with the portable battery pack. The mobile phone 2130 can be, for example, an Android™ phone, an Apple® iPhone®, or a Samsung® Galaxy® phone. Likewise, the tablet 2132 can be any tablet that (1) is capable of running mobile applications and (2) is capable of communicating with the portable battery pack. The tablet 2132 can be, for example, the 3G or 4G version of the Apple® iPad®.

Further, in SOC system 2500, the mobile phone 2130 and/or the tablet 2132 is in communication with a cellular network 2516 and/or a network 2514. The network 2514 can be any network for providing wired or wireless connection to the Internet, such as a local area network (LAN) or a wide area network (WAN).

An SOC mobile application 2512 is installed and running at the mobile phone 2130 and/or the tablet 2132. The SOC mobile application 2512 is implemented according to the type (i.e., the operating system) of mobile phone 2130 and/or tablet 2132 on which it is running. The SOC mobile application 2512 is designed to receive SOC information from the portable battery pack. The SOC mobile application 2512 indicates graphically, audibly, and/or tactilely, the state of charge to the user (not shown).

FIG. 20B illustrates a block diagram of an example of SOC system 2520 of the portable battery pack that is capable of communicating with the SOC mobile application 2512. In this example, the SOC system 2520 includes an SOC portion 2522 and a communications portion 2524. The SOC portion 2522 is substantially the same as the control electronics 2430 shown in FIG. 19. The communications portion 2524 handles the communication of the SOC information to the SOC mobile application 2512 at, for example, the mobile phone 2130 and/or the tablet 2132.

The communications portion 2524 includes a processor 2526 that is communicatively connected to the communications interface 2510. The digital output of the ADC 2434 of the SOC portion 2522, which is the SOC information, feeds an input to the processor 2526. The processor 2526 can be any controller, microcontroller, or microprocessor that is capable of processing program instructions. One or more batteries 2528 provide power to the processor 2526 and the communications interface 2510. The one or more batteries 2528 can be any standard cylindrical battery, such as quadruple-A, triple-A, or double-A, or a battery from the family of button cell and coin cell batteries. A specific example of a battery 2528 is the CR2032 coin cell 3-volt battery.

In SOC system 2520, the SOC portion 2522 and the communications portion 2524 operate substantially independent of one another. Namely, the communications portion 2524 is powered separately from the SOC portion 2522 so that the communications portion 2524 is not dependent on the presence of the input voltage VIN at the SOC portion 2522 for power. Therefore, in this example, the communications portion 2524 is operable to transmit information to the SOC mobile application 2512 at any time. However, in order to conserve battery life, in one embodiment the processor 2526 is programmed to be in sleep mode when no voltage is detected at the input voltage VIN at the SOC portion 2522 and to wake up when an input voltage VIN is detected. Alternatively, the processor 2526 is programmed to periodically measure the SOC and send SOC information to the SOC mobile application 2512 on the at least one remote device periodically, such as every hour, regardless of the state of input voltage VIN.

FIG. 20C illustrates a block diagram of another example of control electronics 2530 of the portable battery pack that is capable of communicating with the SOC mobile application 2512. In this example, the operation of the communications interface 2510 is dependent on the presence of a voltage at input voltage VIN. This is because, in control electronics 2530, the communications interface 2510 is powered from the output of voltage sensing circuit 2432. Further, the processor 2436 provides the input (i.e., the SOC information) to the communications interface 2510. A drawback of the control electronics 2530 of FIG. 20C as compared with the SOC system 2520 of FIG. 20B, is that it is operable to transmit SOC information to the SOC mobile application 2512 only when the portable battery pack has a charge.

In summary and referring now to FIG. 1 through FIG. 20C, the present invention provides a portable battery pack including a wearable pouch and one or more batteries enclosed in the wearable pouch, wherein the pouch has a first side and an opposite second side, a closable opening through which the one or more batteries can be fitted into the pouch, one or more openings through which one or more leads from the one or more batteries can be accessed, and wherein the pouch includes a pouch attachment ladder system (PALS) adapted to attach the pouch to a load-bearing platform.

In certain embodiments, the portable battery pack is Modular Lightweight Load-carrying Equipment (MOLLE)-compatible. In yet more certain embodiments, the pouch attachment ladder system is formed of a plurality of straps, a plurality of horizontal rows of webbing, a plurality of slits, and combinations thereof.

In some embodiments, the one or more batteries include a battery element, a battery cover, and a battery back plate. In particular embodiments, one or more of the battery element, battery cover, and battery back plate have a curvature or contour adapted to conform to a curvature or contour of the load-bearing platform.
